' To all whom it may concern claim; bu

Be it known that I Gnonon L. Moonn, a

citizen of the United states, residin at Chicago, in the county of Cook and tats of Illinois, have invented a certain new and useful Im rovement in Si ht-Feed Lubricators for utomobiles, anc declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to makeand use the same, reference being had to the accompanyin drawings, which form a art of this speci cation. 7

the Ford automobiles there is no provision made for clearly indicatin to the driver the condition of the oil in t e crank case. The object of the resent invention is to produce a simple and novel attachment by means of which an indication will be made at the dashboard or at some other convenient point, of t e presence of an amount of 011 above the danger point in the crank case of the engine of a Ford automobile or a similar engine. A further object of the resent invention is to roduce an automatic feed of the oil from t e bottom of the crank case of a Ford en 'ne or the like to parts to be lubricated, at t e same time make the flow of the oil visible to the driver.

The various features of novelty whereby my invention is characterized wlll hereinafter he ointed out particularly in the tPfor a full understanding of my invention, and of its objects and advantages, reference may be had to the following detailed description taken in connection with t e accompanying drawing.

Fig. 2 is a. section taken'approximately on line 2-2 of Fig. 1, and

that the 011 which is carried of an automobile en- In accordance withmy invention, I place beside the engine, preferably under the hood 4, an oil conduit 5. The lower end of the conduit may conveniently be screwed through the wall of the crank casing as best shown in Fig. 2, preferably in the plane of that the free end of the con duit may be brought close to the fly-wheel. The part of the conduit within the crank case, in the vicinity of the wheel, is preferably approximate y radial to the fly-wheel and, as best indicated in Fig. 3, is provided on the under side with a slot 6. The conduit is placed on the side of the fly-wheel which carries oil upwardly from the bottom of the crank case and is preferably so positioned upwardly as far as the conduit enters the slot 6 in the conduit under considerable pressure or momentum and may therefore be caused to travel a considerable distance through the conduit.

The oil conduit is carried u behind the dash and communicates with t e u per end of a transparent tube or box 7, placed on the front side of the dash. A discharge conduit 8 leads from the lower end of the member 7 back to the engine. The conduit 8 may discharge into the crank case at any suitable point, but is preferably carried to the front end of the engine so as to dis charge upon the "ears 9 found at that point; thus automatically lubricating these gears in a positive manner as long ficie-nt oil in the crank case to enable the flywheel to carry some of it upwardly and force it through the conduits.

the fly-wheel so as there is suf- As long as there is sufiicient oil in the crank case to Insure proper lubrication, the fly-wheel will be able to feed the oil through the conduits 5 and 8, such flow being visible to the driver by reason of the indicator 7. As soon as the oil drops below the danger point, the feed of the oil ceases, and the driver is instantly apprised of the fact.

ile I have illustrated and described with particularity only a single preferred form of my invention, I do not desire to be limited to the exact structural details thus illustrated and described; but intend to cover all forms and arrangements which fall within the terms of the definitions of my invention constituting the appended claim.
